.RI toc-file
.SH DESCRIPTION
.I cdrdao
creates audio and data CD-Rs in disk-at-once (DAO) mode driven by a description
file called
.I toc-file.
In DAO mode it is possible to create non standard track pre-gaps that
have other lengths than 2 seconds and contain nonzero audio
data. This is for example useful to divide live recordings into
tracks where 2 second gaps would be kind of irritating.

Instead of a
.I toc-file
a cue file (used by a famous DOS/Windows mastering tool) may be used. See
the CUE FILES section for more details. 

.SH COMMANDS
.TP
The first argument must be one of the following commands:
.TP
.BI show-toc
Print out a summary about what will be written to the CD-R.  
.TP
.BI toc-info
Prints out short toc-file summary.
.TP
.BI toc-size
Prints total number of blocks for toc.
.TP
.BI read-toc
Analyze each track of the inserted CD and create a
.I toc-file
that can be used to make a more or less exact copy of the CD. 
This command does not read out the audio or data tracks,
use
.BI read-cd
for this purpose.

You can specify a filename for the data file via the
.BI \--datafile
option.
.TP
.BI read-cd
Copies all tracks of the inserted CD to an image file and creates a corresponding
.I toc-file.
The name of the image file defaults to "data.bin" if no
.BI --datafile
option is given.
.TP
.BI read-cddb
Tries to retrieve title and artist data from a CDDB server for the CD
represented by the given toc-file. The retrieved data is added as CD-TEXT
data for language 0 to the toc-file. Existing CD-TEXT data for language 0 will
be overwritten.
.TP
.BI show-data
Print out all samples that would be written to the CD-R. Each line
contains the sample number (starting at 0) and the decimal sample
value for the left and right channel. Useful to check if the byte
order of audio files is correct.
.TP
.BI read-test
Check if all data can be read from the audio files that are defined in
the
.I toc-file.
This will also check the communication with the slave process that is
responsible for writing the audio data to the CD-recorder. Mainly used
for testing.
.TP
.BI disk-info
Shows information about the inserted CD-R. If the CD-R has an open session
it will also print the start of the last and current session which is
used by mkisofs to create an image for a second or higher session.
.TP
.BI discid
Prints out CDDB information.
.TP
.BI msinfo
Shows information required for creating multi session disks with
mkisofs. The output is meant for processing by scripts.
.TP
.BI drive-info
Shows drive information.
.TP
.BI unlock
Tries to unlock the recorder device after a failed write or simulation
run. If you cannot eject the CD after a cdrdao run try this command.
.TP
.BI blank
Blanks a CD-RW. The CD-RW is minimally blanked by default. Use option
.BI --blank-mode
to select another blanking mode.
Sometimes the blanking speed must be manually reduced for a successful
blanking operation. Use option
.BI --speed
to select another blanking speed.
.TP
.BI scanbus
Scan for devices.
.TP
.BI simulate
Like
.BI write
but laser stays cold. It is a shortcut for
.BI "write --simulate."
.TP
.BI write
Write the CD-R according to the specifications in the
.I toc-file.
.TP
.BI copy
Performs all steps to copy a CD. The device containing the source CD must
be specified with option
.BI --source-device
and the recorder device with option
.BI --device.
If only a single device is available the option
.BI --source-device
must be omitted and cdrdao will prompt to insert the CD-R after an image
of the source CD was created.

The image file with name "cddata<pid>.bin" will be created in the current
working directory if no
.BI --datafile
option is given. The created image will be removed after it has been
written.

If option
.BI --on-the-fly
is given no image file is created and the data will be directly piped from
the reading device to the CD recorder.


.SH OPTIONS
.TP
.BI \--device " [prot:]bus,id,lun"
Sets the SCSI address of the CD-recorder in form of a bus/id/lun
triple, e.g. '0,2,0' for the logical unit 0 of SCSI device with ID 2
on bus 0. ATAPI devices can be specified by using the prefix 'ATAPI:',
e.g. 'ATAPI:0,0,0'. On some systems a device node may be specified
directly, e.g. '/dev/sg0' on Linux systems. Linux 2.6 users may also
try the newer ATAPI interface with the 'ATA:' prefix.
.TP
.BI \--source-device " [prot:]bus,id,lun"
Like above but used for the
.BI copy
command to specify the source device.
.TP
.BI \--driver " driver-id:option-flags"
Force usage of specified driver instead of the automatically
determined driver. Available driver IDs:
.br
cdd2600, plextor, plextor-scan, generic-mmc, generic-mmc-raw,
ricoh-mp6200, yamaha-cdr10x, teac-cdr55, sony-cdu920, sony-cdu948,
taiyo-yuden, toshiba.
.br
Specifying an illegal driver ID will give a list of available drivers.
Option flags may be used to modify the behavior of some drivers. See
.BI README
for details.
.TP
.BI \--source-driver " driver-id:option-flags"
Like above but used for the device specified with option
.BI --source-device.
.TP
.BI \--speed " value"
Set the writing speed to
.I value.
Default is the highest possible speed.
.TP
.BI \--blank-mode " mode"
Sets the blanking mode. Available modes are
.BI full
and
.BI minimal.
Please consider that the data of minimally blanked disks may be easily
recovered. Use the
.BI full
blanking mode for completely erasing all data. The default blanking mode
is
.BI minimal.
.TP
.BI \--datafile " file"
Used for
.BI "read-toc, read-cd"
and
.BI copy.
Set the default data file placed in the toc-file by
.BI read-toc.
Use "-" to indicate STDIN.
For commands
.BI read-cd
and
.BI copy
it specifies the name of the created image file.
.TP
.BI \--read-raw
Only used for commands
.BI read-cd
and
.BI read-toc.
All data sectors will be written as 2352 byte blocks including the sector
header and L-EC data to the image file. The track mode will be set to
MODE1_RAW or MODE2_RAW in the created
.I toc-file.
.TP
.BI \--read-subchan " mode"
Used by commands
.BI read-cd,
.BI read-toc
and
.BI copy.
Specifies the type of sub-channel data that is extracted from the source CD
and written to the track image or copied to the destination CD.
Mode may be
.BI rw
for reading packed R-W sub-channel data (de-interleaved and error
corrected)
and
.BI rw_raw
for reading raw R-W sub-channel data (not de-interleaved, not error
corrected, L-EC data included in the track image).
If this option is not specified no sub-channel data will be extracted.
.TP
.BI \--no-mode2-mixed
Only used for commands
.BI read-cd
and
.BI read-toc.
If we have MODE2_FORM1 or MODE2_FORM2, don't extract it as MODE2_FORM_MIX.
.I toc-file.
.TP
.BI \--tao-source
This option indicates to the commands
.I read-toc
and
.I read-cd
that the source CD was written in TAO mode. It will be assumed that the
pre-gap length between all tracks (except between two audio tracks) is
the standard 150 blocks plus the number of link blocks (usually 2). The
number of link blocks can be controlled with option
.I --tao-source-adjust.

Use this option only if 
.I read-toc
or
.I read-cd
give error messages in the transition areas between two tracks. If you use
this option with pressed CDs or CDs written in DAO mode you will get wrong
results.
.TP
.BI \--tao-source-adjust " link-blocks"
Specifies the number of link blocks for tracks written in TAO mode. This
option has only an effect if option
.I --tao-source
is given.
.TP
.BI \--fast-toc
Only used for command
.BI read-toc.
This option suppresses the pre-gap length and index mark extraction
which
speeds up the read-toc process. Standard 2 second pre-gaps (but no
silence!) will be placed into the toc-file. The resulting CD will
sound like the source CD. Only the CD player's display will behave
slightly different in the transition area between two tracks.

This option might help, too, if read-toc fails with your drive otherwise.

.TP
.BI \--buffers " buffer-count"
Specifies the number of buffers that are allocated to avoid buffer under runs.
The minimal buffer count is fixed to 10, default is 32 except
on FreeBSD systems, on which default is 20.
Each buffer holds 1 second of audio data so that dividing
.I buffer-count
by the writing speed gives the maximum time for which reading of audio data
may be stalled.
.TP
.BI \--multi
If this option is given the session will not be closed after the audio data
is successfully written. It is possible to append another session on such
disks, e.g. to create a CD-EXTRA.
.TP
.BI \--overburn
By default cdrdao will not allow to write more data on a medium than
specified by the current medium. This option allows one to ignore this condition.
.TP
.BI \--eject
Eject the CD-R after writing or write simulation.
.TP
.BI \--swap
Swap the byte order of all samples that are send to the CD-recorder.
.TP
.BI \--session " session-nr"
Used for
.BI read-toc
and
.BI read-cd
to specify the session which should be processed on multi session CDs.
.TP
.BI \--reload
Indicates that the tray may be opened before writing without prompting
the user to reset the disk status after a simulation run.
.TP
.BI \--force
Forces the execution of an operation that otherwise would not be
performed.
.TP
.BI \--paranoia-mode " mode"
Sets the correction mode for digital audio extraction. 0: No checking,
data is copied directly from the drive. 1: Perform overlapped reading
to avoid jitter. 2: Like 1 but with additional checks of the read
audio data. 3: Like 2 but with additional scratch detection and
repair.

The extraction speed reduces from 0 to 3.

Default is the full paranoia mode (3).
.TP
.BI \--keepimage
If a CD is copied with command
.I copy
this option will cause that the created image is not removed after the
copy process has finished. 
.TP
.BI \--on-the-fly
Perform CD copy on the fly without creating an image file.
.TP
.BI \--with-cddb
Enables the automatic fetching of CDDB data for use as CD-TEXT data for
commands
.I copy,
.I read-toc
and
.I read-cd.
.TP
.BI \--cddb-servers " server-list"
Sets space or ',' separated list of CDDB servers used for command
.I read-cddb
or for commands where the
.I --with-cddb
option is active.
A server entry may have the following forms:
.IP <server>
Connect to <server>, default cddbp port (888), use cddbp protocol.
.IP <server>:<port> 
Connect to <server>, port <port>, use cddbp protocol.
.IP <server>:<cgi-bin-path>
Connect to <server>, default http port (80), use http protocol,
url: <cgi-bin-path>.
.IP <server>:<port>:<cgi-bin-path>
Connect to <server>, port <port>, use http protocol, url: <cgi-bin-path>.
.IP <server>:<port>:<cgi-bin-path>:<proxy-server>
Connect to <proxy-server>, default http port (80), use http protocol,
url: http://<server>:<port>/<cgi-bin-path>.
.IP <server>:<port>:<cgi-bin-path>:<proxy-server>:<proxy-port>
Connect to <proxy-server>, port <proxy-port>, use http protocol,
url: http://<server>:<port>/<cgi-bin-path>.

The <cgi-bin-path> is usually "/~cddb/cddb.cgi".

All servers of the server list will be tried in the given order until a
successful connection can be established. For http proxy servers
the first successful connected http proxy server will be used independent of
the ability to connect to the target http server.

Example: freedb.freedb.org:/~cddb/cddb.cgi
.TP
.BI \--cddb-timeout " timeout"
Sets the timeout in seconds used for connections to CDDB servers.
.TP
.BI \--cddb-directory " directory"
Specifies the local CDDB database directory where fetched CDDB records will
be stored. If this option is not given a fetched CDDB record will not be stored
locally.
.TP
.BI \--tmpdir " directory"
Specifies the directory in which to store temporary data files created from decoding MP3 and Ogg Vorbis files. By default, "/tmp" is used.
.TP
.BI \--keep
Upon exit from cdrdao, do not delete temporary WAV files created from MP3 and Ogg Vorbis files.
.TP
.BI \--save
Saves some of the current options to the settings file
"$HOME/.cdrdao" and exit. See section \'SETTINGS\' for more details.
.TP
.BI \-n
Suppresses the 10 second pause before writing or simulating.
.TP
.BI \-v " verbose-level
Sets verbose level. Levels > 2 are debug levels which produce a lot of
output.

.SH "TOC FILES"
The
.I toc-file
describes what data is written to the CD-R and allows control
over track/index positions, pre-gaps and sub-channel information. It
is a simple text file, use your favorite text editor to create it.

A
.I toc-file
contains an optional header and a sequence of track
specifications. Comments starting with '//' reaching until end of line can be
placed anywhere.

.SS Header
.IP CATALOG\ "ddddddddddddd"
Specifies the optional catalog number of the CD. The string must
contain exactly 13 digits.
.LP
The following flags specify the type of session that will be created. It
is used to create the correct CD-TOC format and to check the consistency of
the track modes for the desired session type. If multiple flags are given
the last one will take effect.
.IP CD_DA 
The disc contains only audio tracks.
.IP CD_ROM
The disc contains just mode 1 tracks or mode 1 and audio tracks (mixed
mode CD).
.IP CD_ROM_XA
The disc contains mode 2 form 1 or mode 2 form 2 tracks. Audio tracks
are allowed, too. This type must be used if multi session disks are
created (option \-\-multi).
.IP CD_TEXT\ {\ ...\ }
Defines global CD-TEXT data like the album title and the used languages.
See the CD-TEXT section below for the syntax of the CD-TEXT block contents.
.SS Track\ Specification
.IP TRACK\ <track-mode>\ [<sub-channel-mode>]
Starts a new track, the track number is incremented by 1. The length
of a track must be at least 4 seconds. The block length of the input
data depends on the <track-mode>: AUDIO: 2352 bytes (588 samples),
MODE1: 2048 bytes, MODE1_RAW: 2352 bytes, MODE2: 2336 bytes,
MODE2_FORM1: 2048 bytes, MODE2_FORM2: 2324 bytes, MODE2_FORM_MIX: 2336 bytes
including the sub-header, MODE2_RAW: 2352 bytes.
The <sub-channel-mode> is optional. If given it specifies the type of
sub-channel data for each sector. RW: packed R-W sub-channel data (96
bytes, L-EC data will be generated if required), RW_RAW: raw R-W
sub-channel data (interleaved and L-EC data already calculated, 96
bytes). The block length is increased by the sub-channel data length
if a <sub-channel-mode> is specified.
If the input data length is not a multiple of the block length  it
will be padded with zeros. 
.LP
The following flags may follow the track start statement. They are
used to set sub-channel information for the current track. Each flag
is optional. If not given the following defaults are used: copy not
permitted, no pre emphasis, two channel audio, no ISRC code. 
.IP "[ NO ] COPY"
Sets or clears the copy permitted flag. 
.IP "[ NO ] PRE_EMPHASIS"
Sets or clears the pre emphasis flag (only for audio tracks).
.IP TWO_CHANNEL_AUDIO
Indicates that track contains two channel audio data (only for audio tracks).
.IP FOUR_CHANNEL_AUDIO
Indicates that track contains four channel audio data (only for audio tracks).
.IP ISRC\ "CCOOOYYSSSSS" 
Sets ISRC code of track (only for audio tracks).
.br
C: country code (upper case letters or digits)
.br
O: owner code (upper case letters or digits)
.br
Y: year (digits)
.br
S: serial number (digits)
.LP
An optional CD-TEXT block that defines the CD-TEXT data for this track
may follow. See the CD-TEXT section below for the syntax of the CD-TEXT
block contents.
.IP "CD_TEXT { ... }"
.LP
At least one of the following statements must appear to specify the
data for the current track. Lengths and start positions may be
expressed in samples (1/44100 seconds) for audio tracks or in bytes
for data tracks. It is also possible to give the length in blocks
with the MSF format 'MM:SS:FF' specifying minutes, seconds and frames
(0 <= 'FF' < 75) . A frame equals one block. 

If more than one statement is used the track will be composed by
concatenating the data in the specified order.
.IP "SILENCE <length>"
Adds zero audio data of specified length to the current audio track. 
Useful to create silent pre-gaps.
.IP "ZERO <length>"
Adds zero data to data tracks. Must be used to
define pre- or post-gaps between tracks of different mode.
.IP [\ FILE\ |\ AUDIOFILE\ ]\ "<filename>"\ <start>\ [\ <length>\ ]
Adds the audio data of specified file to the current audio track. It
is possible to select a portion of an audio file with <start> and
<length> which allows non destructive cutting. The first sample of an
audio file is addressed with <start> = 0. If <length> is omitted or
set to 0 all audio data from <start> until the end of file is used.

Audio files may have raw or WAVE format with 16 bits per sample, 44.1
kHz sampling rate, stereo. Raw files must have the layout 'MSBLeft
LSBLeft MSBRight LSBRight ...' (big endian byte order). WAVE files are
expected to have little endian byte order. The option \-\-swap reverses
the expected byte order for all raw and WAVE files. Only filenames
with a ".wav" ending are treated as WAVE files, all other names are
assumed to be raw audio files. Use tools like sox(1) to convert other
file formats to supported formats.

Specifying a "-" as filename causes data to be read from STDIN. Currently
only raw files are supported from STDIN.
 
If you are unsure about the byte order of your audio files try the
command 'show-data'. If the byte order is correct you will see a
sequence of increasing or decreasing numbers for both
channels. Otherwise numbers are jumping between very high and low
values - high volume static.
.IP DATAFILE\ "<filename>"\ [\ <length>\ ]
Adds data from given file to the current data track. If <length> is omitted
the actual file length will be used.
.IP FIFO\ "<fifo\ path>"\ <length>
Adds data from specified FIFO path to the current audio or data track.
<length> must specify the amount of data that will be read from the
FIFO. The value is always in terms of bytes (scalar value) or in terms
of the block length (MSF value).
.IP "START [ MM:SS:FF ]"
Defines the length of the pre-gap (position where index switches from
0 to 1). If the MSF value is omitted the current track length is
used. If the current track length is not a multiple of the block
length the pre-gap length will be rounded up to next block boundary.

If no START statement is given the track will not have a pre-gap.
.IP "PREGAP MM:SS:FF"
This is an alternate way to specify a pre-gap with zero audio data. It
may appear before the first SILENCE, ZERO or FILE statement. Either PREGAP
or START can be used within a track specification. It is equivalent to
the sequence
.br
  SILENCE MM:SS:FF
.br
  START
.br
for audio tracks or
.br
  ZERO MM:SS:FF
.br
  START
.br
for data tracks.
.LP
Nothing prevents mixing 'DATAFILE'/'ZERO' and 'AUDIOFILE'/'SILENCE'
statements within the same track. The results, however, are undefined.


The end of a track specification may contain zero or more index
increment statements:
.IP "INDEX MM:SS:FF"
Increments the index number at given position within the track. The
first statement will increment from 1 to 2. The position is relative
to the real track start, not counting an existing pre-gap.

.SS CD-TEXT Blocks
A CD-TEXT block may be placed in the global section to define data valid for
the whole CD and in each track specification of a
.I toc-file.
The global section must define a language map that is used to map a
.I language-number
to country codes. Up to 8 different languages can be defined:
.IP "LANGUAGE_MAP { 0 : c1  1 : c2  ...  7 : c7 }"
The country code may be an integer value in the range 0..255 or one of the
following countries (the corresponding integer value is placed in braces 
behind the token): EN(9, English)
.br
It is just necessary to define a mapping for the used languages.
.LP
If no mapping exists for a
.I language-number
the data for this language will be ignored.

For each language a language block must exist that defines the actual data
for a certain language.
.IP "LANGUAGE language-number { cd-text-item cd-text-data cd-text-item cd-text-data ... }"
Defines the CD-TEXT items for given
.I language-number
which must be defined in the language map. 
.LP

The
.I cd-text-data
may be either a string enclosed by " or binary data like
.nf
.in +.5i
{ 0, 10, 255, ... }
.in -.5i
.fi
where each integer number must be in the range 0..255.
.br
The
.I cd-text-item
may be one of the following:
.IP TITLE
String data: Title of CD or track.
.IP PERFORMER
String data.
.IP SONGWRITER
String data.
.IP COMPOSER
String data.
.IP ARRANGER
String data.
.IP MESSAGE
String data. Message to the user.
.IP DISC_ID
String data: Should only appear in the global CD-TEXT block. The format is
usually: XY12345
.IP GENRE
Mixture of binary data (genre code) and string data. Should only appear in
the global CD-TEXT block. Useful entries will be created by
.I gcdmaster.
.IP TOC_INFO1
Binary data: Optional table of contents 1. Should only appear in the global
CD-TEXT block.
.IP TOC_INFO2
Binary data: Optional table of contents 2. Should only appear in the global
CD-TEXT block.
.IP UPC_EAN
String data: This item should only appear in the global CD-TEXT block. Was
always an empty string on the CD-TEXT CDs I had access to.
.IP ISRC
String data: ISRC code of track. The format is usually: CC-OOO-YY-SSSSS
.IP SIZE_INFO
Binary data: Contains summary about all CD-TEXT data and should only appear
in the global CD-TEXT block. The data will be automatically (re)created when
the CD-TEXT data is written.

If one of the CD-TEXT items TITLE, PERFORMER, SONGWRITER, COMPOSER, ARRANGER,
ISRC is defined for at least on track or in the global section it must be
defined for all tracks and in the global section. If a DISC_ID item is defined
in the global section, an ISRC entry must be defined for each track.

.SH CUE FILES

Cue files may be used wherever a
.I toc-file
is expected. The corresponding bin file is not taken from the FILE statement
of a cue file but constructed from the cue file name by replacing ".cue" by
".bin". The cue file must have exactly one FILE statement.

Currently, following track modes are supported: MODE1/2048, MODE1/2352,
MODE2/2336, MODE2/2352. The CATALOG, ISRC and POSTGAP statements are
parsed but not evaluated, yet. 

.SH SETTINGS

Some of the command line options can be stored as settings at
following locations. The files will be read on startup of
